Example prompt: Can you audit my OpenWeather Road Risk API JSON change — here's the before document and the after document — and tell me which paths were added, removed, or changed, and whether any new schema errors were introduced or old ones resolved?

## When to prefer this

Choose this endpoint when you need to audit schema compliance changes specifically for the OpenWeather Road Risk API JSON format, comparing a before and after document to surface exactly which paths changed and whether validation errors were introduced or resolved. Prefer it over generic JSON diff tools when Road Risk API schema correctness matters and you want rule-violation reporting tied to a pinned SchemaStore definition.

## Known failure modes

- Document exceeds 100 KB limit — request rejected
- JSON nesting exceeds 32 levels — request rejected
- Invalid JSON submitted (YAML or TOML not supported) — parse error returned
- Malformed request body — validation error
- Payment not completed — endpoint inaccessible
